Dayun Truck A/C Compressors

What Dayun truck compressor coverage is available?

This category currently covers two catalog-controlled Dayun truck applications: one referenced by 80620601 and one identified for the Dayun D120. Both use a 10PA17C family, four-rib clutch near 120 mm and a 12V coil, but matching headline dimensions do not prove that the two assemblies share every mounting and head detail.

Why keep both identities in the inquiry?

Listing the reference-led and D120 applications separately prevents a buyer from treating one accepted sample as automatic approval for the other truck.

How should reference 80620601 be used?

Use 80620601 as one identification anchor together with photographs and physical configuration. A reference can be superseded, copied into aftermarket catalogs or attached to variants with different connectors and hose heads. The safest RFQ combines the number with Dayun vehicle information, clutch data, mounting geometry and the removed-unit label.

What if the number is unreadable?

Send vehicle model and production information plus clear front, side, rear and connector photographs. Measurements can replace missing label data, but uncertainty should remain visible.

Can the D120 and reference-led units be interchanged?

Not without evidence. The shared PV4, 120 mm and 12V description narrows the search but does not settle foot spacing, body offset, port clocking, connector lead or previous service changes. Treat them as a variant pair until a drawing, controlled cross-reference or side-by-side sample inspection proves equivalence.

Which differences cause the most workshop delay?

Wrong head direction, pulley offset and mounting width often appear only during installation, after freight and inventory costs have already been incurred.

What should fleet buyers inspect on the removed compressor?

Record voltage, four-rib clutch, pulley diameter, mounting ears, connector type, hose-port direction and seal style. Photograph belt alignment before removal and note any bracket spacer. Also diagnose the fan, condenser, hoses and refrigerant circuit so an unrelated system fault is not attributed to the replacement compressor.

Should the clutch be tested separately?

Yes. Check coil resistance and engagement with the correct 12V supply, while respecting safe workshop procedures and the compressor supplier’s test guidance.

What information makes wholesale offers comparable?

Ask each supplier for the exact offered configuration, product condition, current photographs, sample terms, quantity breaks, lead time, packing, labeling and claim process. Require any substitution to be disclosed before shipment. A lower price is not comparable when the response omits clutch, port or mounting evidence that another quotation includes.

How should repeat orders be controlled?

Retain the approved sample record and compare incoming labels, clutch, head orientation, connector and packing with it before releasing the batch to regional stock.

How can Elecdurauto quote Dayun truck compressors?

As an aftermarket supplier, Elecdurauto can review a Dayun RFQ for distributor, fleet or repair-network demand. Provide the 80620601 reference or D120 application, old-unit images, vehicle data, required quantity, destination and acceptance points. The response can then separate technical confirmation from commercial terms and identify any sample-stage question.

What buyer details help with planning?

Include annual demand, order split, preferred carton marks, shipping term and whether the units will support one fleet or multi-country wholesale distribution.
